This workout comes from an unexpected, albeit well-known place. Bowflex. Yes that’s right, this no-equipment at-home cardio fat blast is from the team at Bowflex and let me tell you, it is killer! Using high intensity moves and a rapid pace, you’ll be melting fat away in just five minutes. That being said, I would try it once at home before doing it on a coffee break at work because even though you may have the time, sitting back down at your desk looking like a sweaty mess may ruin the desired effect. Enjoy!
